When a user wants to add a new printer it's asking for a root password. I have an LTSP environment and the system is asking for a root password all the time; it's not asking even for a sudo'ed user's password. Is there any way to allow a certain user to add/edit/remove printers and not to have any other special access?

Have a look at the files in /etc/cups

I do not have a Fedora 15 system to hand - but looking at a recent RHEL box, the relevant bits are in /etc/cups/cupsd.conf

# Administrator user group...
SystemGroup sys root
# Restrict access to configuration files...
<Location /admin/conf>
  AuthType Basic
  Require user @SYSTEM
  Order allow,deny
  Allow localhost
 # All administration operations require an adminstrator to authenticate...
<Limit Pause-Printer Resume-Printer Set-Printer-Attributes Enable-Printer 
     Disable-Printer Pause-Printer-After-Current-Job Hold-New-Jobs 
     Release-Held-New-Jobs Deactivate-Printer Activate-Printer 
     Restart-Printer Shutdown-Printer Startup-Printer Promote-Job 
     Schedule-Job-After CUPS-Add-Printer CUPS-Delete-Printer 
     CUPS-Add-Class CUPS-Delete-Class CUPS-Accept-Jobs 
     CUPS-Reject-Jobs CUPS-Set-Default>
  AuthType Basic
  Require user @SYSTEM
  Order deny,allow

IIRC, @SYSTEM is a macro for the groups listed in SystemGroup

    For CentOS 7 (release 1810), the SystemGroup definition appears in /etc/cups/cups-files.conf instead of with the cupsd.conf daemon setup shown above. On many systems, simply adding group wheel to the SystemGroup definition will grant printer-configuration privileges to all administrators and sudo users. The system required a reboot for the new SystemGroup to take effect -- the cups service was unable to respond to a systemctl reload command. Jan 6, 2019 at 2:17

Add the user to the lp group. If that doesn't work, check ls -l /dev/_your_printer_ and see which group owns it

  • Thank you! Currently the problem is that so the printers are network printers. And not local. So they wouldn't appear in /dev/ folder.

  • are you using cups? if yes - adding user to lp group and managing printer via cups should solve problem

If you're using winbind to connect to an active directory, you can also specify an active directory group by prefixing with an @. For example @PrintOperators ...
